About this 1.3ct lab-grown oval diamond

This 1.3ct lab-grown oval sits in the one-and-a-quarter to one-and-a-half carat band, graded E colour (colourless) and VVS1 clarity (very-very-slightly-included), with a top-tier cut grade and certified by IGI LG805641709 or 805641709. Listed at 3 retailers as of October 28, 2026, with a relatively tight 13% spread, which is unusual at this carat range and suggests competitive pricing across the listings.
